WALLACE R. BROWN', OF CLEAN, NEW YORK.`

KNIFE.

Application led February 3, 1923. Serial No. 616,744.

i kTo all whom t may concern:

Beit known that I, WALLACE R. Bno'wiv, a citizen of theUnited.l Statesof America, and a resident of` Olean, yin the county of CattaraugusandState 'of New York, have "invented a new land Improved Knife, of

which the following is a description.

My invention relates to'clasp knives and more .particularly relates to aknife the blade of which is pivotally carried by a sheath swingable intoor out of the knife handle for the positioning` of the blade for use orfor the sheathing of the blade when the knife is not required foruse.

The invention especially relates to novel locking means adapted both tohold the knife in the handle in the completely closed.`

position of theV knife or to engage an l hold the blade projecting at anend of the handle.

The nature o-f the invention, its distinguishing features and advantageswill clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a side elevation of a knife embodying my invention showingthe same in the closed position;

Figure 2 is a side elevation of the knife with the sheath swungoutwardly from the handle, the blade being shown in the sheath;

Figure 3 is a view similar to Figure 2 but showing the blade swung outof the sheath. and the sheath swung out of the handle preparatory topositioning and locking the blade for use;

Figure 4 is a side elevation of the knife with the blade positioned foruse and locked;

Figure 5 is a back view of the knife in the closed condition of Figure1; j

Figures 6, 7 and 8 are transverse sections on the lines 6-6, 7-7- and8--8, respectively.

In carrying out my invention in practice any approved des-ign may beprovided, said handle adapted to receive a sheath 11 pivoted thereto atone end as at 12 so that the sheath may be swung into the handle or outof the same. A blade 13 is pivoted as at 14 tothe sheath near the freeend and is adapted to fold into the sheath or to `be swung out of thesame, said sheath being U-shaped in cross section.

On the blade 13 at one side ledge near the pivoted end is a laterallyprojecting lug 15 adapted to protrude through a slot 16 in the back 18of the sheath 11, said lug having `a notch 17 for engagement with theback 18 at an end of the slot 16. The slot 17 Vhas another function alsoin that it is adapted for engagement for a U-shaped locking bail 19pivoted to the handle 10 at that end opposite the pivot 12 of thesheath. The bail 19 at the bend thereof has at one edge a projecting lip21 which is adapted to have engagement in the slot 17 when the knifeblade 13 is positioned atY an end of the handle for use. j' Y j With thedescribed construction when the sheath with the blade therein is swiunginto the closed position ,into the handle 10, the bail 19 may be swungon its pivot 2() over the back of the sheath to hold the sheath againstaccidental outward swinging, whereby the knife is securely maintainedclosed. When the knife is to be used the bail 19 is swung away from thesheath leaving the sheath free to be swung on its pivot 21 out of thehandle 10, as for example to the position shown in Figures 2 and 3. Theblade 13 is then swung out of the sheath 1'1 to position in line withthe sheath as Figure 3. The sheath 11 with the blade 13 extending at anend thereof in Figure 3 is now swung on the pivot 12 into the handle 10so that the knife will project at that end of the handle having the bail19 as illustrated in Figure 4. The bail 19 is now moved to a positionfor its latch lip 21 to enter the notch 17 in the lug 15 of blade 13.Hence, said blade cannot swing on its pivot 14.

lVith the knife blade as shown in Figure 4, the sheath 11 with the blade13 thereon must be swung on the pivot 12 in ar direction away from thelip 21 and it will be seen with respect to Figure 4 that the lip 21 whenengaged in the slot 17 of the blade prevents movement of the sheathabout the pivot 12 as. an axis. Thus, it will he seen that the onelocking bail 19 serves to secure the knife in the closed position aswell as serving to hold the blade in the open position for use.

The lip 22 is formed on the hail 19 at approximately right angles to thelip 21 and serves as a finger-hold in swinging the bail on its pivot 20.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the exact details herein illustrated, since,manifestly, the same can be considerably varied Without departure fromthe spirit of the invention as defined in the appended claims.

Having thus described my invention, claim:

l. A knife of the class described comprising a handle, a sheath pivotedthereto to swing into or out of the handle, a blade pivoted to thesheath near one end to fold into the sheath or to swing outward in lineWith the sheath, and means von the handle to hold the sheath in thefolded position with the blade closed or to engage the blade and holdthe same in the open position, said means comprising a bail, the bailhaving a locking lip and said blade having a notch to receive said lipWhen the blade is in the open position and the sheath folded into thehandle, the bail being swingable over the back of the sheath when theblade is folded into sheath and the sheath folded into the handle.

2. A knife of the class described comprising a handle, a sheathswingable into or out of the handle, a blade pivoted to the sheathadjacent the free end thereof, a lateral lug therein, and a bail on thehandle at the 'endY opposite the sheath pivot, said bail having a lipadapted to engage` into said notchV of the blade when the blade is inposition for use, said bail being swingable over the back of the sheathWhen the blade is in the closed position of the sheath and the saidsheath folded in the handle.

3. A knife of the class described comprising a handle, a sheathswingable into or out of the handle, a blade pivoted to the sheathadjacent the free end thereof, a lateral lug on the knife at a side edgethereof near the pivot of the blade, said lug having a notch therein,and a bail on the handle'at the end opposite the sheath pivot, said bailhaving a lip adapted to engage into said notch of the blade When theblade is in position forV use, said bail being swingable over the backof the sheath when the blade Yis in the closed position of the sheathand the said sheath' W.
